VENTILATED INsoLE.

Application. led July 6,

My present invention'is a novel and improved ventilated shoe construction, and includes a novel method or process of making the same.` v *l Heretofore many attempts have been made Y to construct ventilated footwear of varying capacity, style and construction, but such prior articles have been objectionable for various reasons. Many attempted ventilated v shoe constructions have been impractical from the manufacturing standpoint, or have involvedextremely difficult and such expensive methods, materials and machines as t0 render them uncommercial. Other objections have been the entire change in shoe manufacturing methods required to carry out the construction required.

In vmy present process I am enabled toconsists in the provisions of a ventilated in' sole and a combined arch supporting cushion and absorbent member. Further features consist in the provision of a smooth heel seat in the interior of the shoe in combination with the ventilated insole structure and the resulting shoe gives the benefit of ventilation, arch supporting, yielding instep or arch cushion, and smooth heel seatand a high grade and preferably welt shoe construction.

A further feature of the present invention consists in the novel insole utilized.' My improved insole 'being first prepared to include the Ventilating` -and cushioning features as well as to incorporate also the nailless heel seat feature, so far as the heel contacting surface of the insole is concerned.

Further features of the invention, novel combinations and the method of making same will be more fully pointed out and claimed. v

Referring to the drawings, illustrating a preferred embodiment wherein my novel ventilated shoe incorporates the new insole and is made in accordance .with my present method of construction; f

Fig.l 7 is a cross-sectional view on the the' line line Referring to the drawings wherein I have illustrated a lwelt shoe construction embodying my invention,`the shoe upper designated generally at lmay be ofany suitable style, form or contour and the shoe is made ,on any desired type or style of last. 2 indicates the outsole, 3 the welt, I preferably employing usual welt shoe construction so far as ast-l ing, inseaming and sole attaching is con` tended to lead directly from the foot-contacting surface of the insole v5 through the same, and into the absorbing and cushioning member 7 positioned on the under side'of the insole andas in the case of a welt insole-between the sewing rib 10. As herein illustrated a usual sewing rib construction is shown wherein two portions of the insole 5 are cut at the margin and turned upwardly for uniting into the `composite rib 10. Preferablyalso this insole may be gemmed, i. e., reinforced with a canvas layer 12 which may .likewise extendinto and be cemented with the composite rib 10. The Ventilating openings 6, 6, extend entirely through the canvas layer l2 to .afford an opening or access completely through that portion of the insole .which is thus perforated, as clearly shown in Figs. 4 and 6. I may apply the cushioning and absorbent layer 7 to the insole before the latter is assembled on the last for incorporation in the shoe, 'or Imay apply the same after the shoe is lasted or even after the lasted shoe 'has been subjected tothe inseam stitching 7'. Furthermore Icom lete the preparation of the insole by splitting the heel ortion as shown at 15, giving an upper eel contacting layer 17 and a lower layer'17 which latter is to receive the heel nails 19, 19, to be clinched therein when' the heel 20 is applied, a`clinching plate 21 being interposed between the two layers to preserve the nailless heel seat surface 17.

With the insole thus prepared, I then ap ply the plate 21 fitting same between the two split portions 17 and 18 of the heel end of the insole. This plate 21 acts as a clinching vplate for the heel nails, both for lasting the heel seat and for clinching the heel holding nails. Thereupon I assemble the insole and upper on a last, last the shoe in the usual manner, unite the Welt 3, upper l and insole rib 10 by the usual inseaming machine, apply such filler as maybe necessary over the orepart of the insole ;-the cushioning and absorbent mass? taking the place of a filler over the perforated portion; and thereupon I apply the outsole and unite same to the shoe. Thereupon theheel 20 is applied and the nailing operation effected, clinching the nails against the plate 21, whereupon the last is pulled, the plate 21 is removed and the upper layer 17 replaced and cemented inpo- K sition if desired. Thus I complete my ventilated, cushioning, and nailless heel seat shoe construction without extra machines,

devices or special or dicult operations.

. asesinos The action of the foot in. walking over the cushioning material 7 acts largely to produceA a suction through the Ventilating recesses 6, as well as to normally absorb any moisture on the insole. -The material 7 may be of an desired or suitable mass -or character, as we l as hei ht if desired to give an arch support ing e ect. Preferably I utilize felt or other absorbent `material which may be readily cutrib, while in a McKay shoe the cushioning and absorbent material would simply -be attached on the inner side of the insole at the ventilated portion.

My invention is further described and defined in the/form of a claim as follows:

A prepared insole for use in the manufacture of welt boots and shoes, having, in combination, a sewing rib around its marginal edge forwardly of the heel portion, a fabric reinforcing layer secured -to the insole and to the sewing rib and occupying the space enclosed by said sewing rib, a plurality of perforations extending throu h the insole and through the reinforcing ayer and located only at the shank portion of the insole, and animperforate layer of yieldin and absorbent material securcd to the reinforcing layer and to the insole and located at lthe shank portion only of the insole, said inperforate layer of yielding land absorbent material being of suicient thickness to act as an arch support.

In testimony whereof, I have signed my name to this specification.
